Abstract

In this work, Organic Light Emitting Diodes using LiF as a electron-injecting interfacial have been fabricated for efficiency enhancements. This interfacial layer is interposed between Al/$Alq_3$ layer. The brightness and specific character as current density are higher than those of the device without it. To find best thickness of LiF layer, we used some samples with various thickness. The LiF interposition at the Al/$Alq_3$ interface encouraged the electrons injection and balances the injection numbers of hole and electron in the emission layer.
